The unexamined tendency to believe that ideas, aesthetics, or sources of information are more valid, credible, or important simply because they are amplified by dominant cultural institutions (corporate media, major publishers, blockbuster studios, top-charting algorithms). It conflates prevalence with quality and popularity with truth. This bias creates a feedback loop where mainstream ideas get more attention because they are mainstream, making alternative perspectives seem fringe by definition, not by merit.
Example: Dismissing a groundbreaking scientific paper because it was published in a specialized journal and not on the cover of Nature or Science is Mainstream Bias. It assumes that the gatekeepers of prestige are infallible arbiters of significance, potentially missing revolutionary work that hasn't yet been blessed by the establishment.
